VEHICLE CONTROL DEVICE Russian patent published in 2019 - IPC B60L15/20 B60L9/18 B60L11/18 H02P27/08 H02P23/28 H02M7/5395 

FIELD: transportation.

SUBSTANCE: group of inventions relates to the electric vehicles traction system control device. Vehicle's electric motor control device comprises modulator, the first correction module, the second correction module, and the controller. Modulator is configured to generate the modulating signals. First correction module performs the first correction process, in which the modulating signals central value is corrected to reduce the losses in the inverter. Second correction module performs the second correction process, in which the third harmonic signal amplitudes shift and phases shift relative to the voltage control signals are reduced. At that, when the AC motor revolutions number is less than the predetermined revolutions number, the controller controls the first correction module so, that to perform the first correction process, if the DC voltage is greater than or equal to the first predetermined voltage, and controls the second correction module so, that to perform the second correction process if the DC voltage is less than the first predetermined voltage.

EFFECT: technical result consists in reduction of the inverter switching elements heating and the electric motor stable control.
